we need clean, safe, single sex loos, for women. Whatever other provision exists for others - I don't care, except I generally hope it works for them and everyone can be happy. Still - not my problem.
This. Very well put.
Removing needed single sex facilities from females excludes and fails female people. The reasons and needs for female people in having single sex spaces haven't gone away. Taking them away to try and meet the needs of another demographic is a ridiculous answer.
Third spaces: easy enough to do and provides a solution for those who prefer not to use facilities intended for their biological sex, plus those perfectly happy to use mixed sex spaces.
This really isn't at all about safety. This is about offering some male people choice and freedom while removing from some female people access to any space at all .
